Application led November 20, V1926. Serial No. 149,746.

This invention relates to refrigerating apparatus, particularly to wallsor closures for refrigerating cabinets, and is especially applicable tocabinets for keeping ice-cream in restaurants, soda fountains and thelike.

An object of the invention is to provide means for maintaining articlescooled by a refrigerating cabinet at a 'higher temperature than thatnormally prevailing in the cabinet.

Another object is to provide improved means for keeping articles cold,yet readily accessible.

Another object-is to provide an improved wall, or a closure forrefrigerating cabinets adapted to receive articles to be cooled.

Further obiects` and advantages will be apparent from the specificationand drawings, in which Fig. 1 shows the invention applied to anice-cream cabinet, and

Fig. 2`is a section on the line 2-2 of F ig. 1.

It is known that a temperature much below the freezing point of water isrequired to keep ice cream satisfactorily. Bottled goods, such as syrupsand beverages, should be cooled, but should be maintained at atemperature appreciably above freezing in order either not to freezesolid or congeal to an undesired consistency. My invention provides asimple and inexpensive means for keeping both these commodities at therequired temperatures in an ordinary icecream cabinet.

Referring to the drawings, 10 represents a conventional ice-creamcabinet having insulating walls 11 and sleeves 12 for the reception ofcylindrical ice-cream cans 13. Brine, or other refrigerating medium, iscirculated in the space between the sleeves. As is usual, the cabinethas a thick insulating top 14, which extends a considerable distanceabove the tops of the cans. Thick insulating covers 15 are usuallyprovided to close the openings over the cans. The present inventioncontemplates a cover 16 having the usual thick insulating portion 17 andmetal linings or facings 18. One or more holes 2() are formed throughthe cover and these are closed by suitable thin, thermalconductingmembers 21, which permit a certain amount of heat to beabsorbed through the cover by the refrigerating. apparatus within. Theseclosure members may consist of any. suitable material, or be of anysuitable vshape or thickness, the choice being dependent upon the nature,of the articles to be cooled and the degree of cooling required. Asshown in the drawings, I may construct them ot' metal cups, which aresecured to the metal linings 18 and project into the interior of thecabinet. TheA distance these cups project into the cabinet influencesthe amount. of heat which can be absorbed through them and,consequently, the degree of cooling applied to the articles storedtherein. In the case lof syrup bottles 23, it is desirable to have thebottom of the cups just above the surface of the ice cream when the cansare full. The bottles project a considerable distance above the top ofthe cabi.,` net and thus absorb heat from the outside atmosphere andprevent the contents from freezing solid or congealing to an undesiredconsistency, as would otherwise take place if the bottles were merelyplaced' in the cabinet.

It is understood that the invention is not limited to the particulardetails whichhave been selected for illustration, but coversmodifications which coine within the scope of the appended claims.

What is claimed is as follows:

1. A refrigerating apparatus having a refrigerating tank, a foodcompartment in said tank and an opening in the top wall of saidapparatus for the insertion or removal of food in the compartment, aclosure lfor said opening, and a heat conducting cell in said closure,being normally open at the top and having thermal contact with saidcompartment for the reception of a container of a substance to becooled.

2. An ice cream cabinet having a sleeve in a refrigerating compartmentfor the reception of anice cream can, a lid over said sleeve, and a heatconducting cell in said lid in thermal contact with said compartmentopen at the top and a bottle partially in said cell adapted to contain asubstance to be cooled to a temperature higher than the temperature insaid compartment.

3. An ice cream cabinet having sleeves in a refrigerating compartmentfor the reception of ice cream cans, lids over said sleeves, and a heatlconducting cell in at least one of said lids in thermall contact withthe sleeve thereunder, and a bottle partially in and eX- tendingupwardly from said cell and adapted to contain a substance to be cooledto a temperature higher than the temperature of said compartment.

4. A refrigerating apparatus having a food compartment therein and anopening in a Wall of said apparatus for the insertion or removal of foodin the compartment, a closure for said opening, and a heat con ductingcell in said closure permanently open externally of said cabinet andhaving thermal contact With said compartment for the reception of abottle or the like adapted to contain a substance to be cooled.

5. An ice cream cabinet having a sleeve in a refrigerating compartmentfor the reception of an ice cream can, a lid over said sleeve, and aheat conducting cell in said lid permanently open externally of saidcabinet in thermal contact with said compartment for the reception of abottle or the like adapted to contain alsubstance to be cooled.

In testimony whereof I hereto aix my signature.
